IMPROVEMENT IN DEVICES FCR LEVELING MILLSTONES.

Specification forming part of Letters Patent No. 139,479, dated June 3, 1873 application led September 9, 1872. p

T o all whom it may concern:

Beit known that I, WALTER RING,'of the county ot' Owen and State ot Indiana, have invented an Improved MillstoneGage.

The follow ing description, taken in connection with the accompanying plate of drawings hereinafter referred to, forms a full and exact specification, wherein are set forth the nature and principles of the invention, by which the same may be distinguished from others ot' a similar class, together with such parts thereof as are claimed as new and are desired to be secured by Letters Patent ot' the United States.

My invention relates to that class of devices which are made use of for gaging, staffing, and leveling millstones and plumbing the spindles thereof; and the nature of said invention consists in certain modifications in the details of the construction ofthe same, whereby the spindle may be set perfectly true and the burrstone be made level.

ln thcaccompanyingplate ofdrawings which illustrate my invention and form a part ot' the specification thereof', Figure lis a view, in perspective, representing the staff applied to the burr. Fig. 2 is a transverse vertical section. Fig. 8 is a plan ofthe bottom of the statt. Fig. 4 illustrates the parts composing the lower chuck. Fig'. 5 is a transverse section on line .fr a* in Fig. 3.

My invention is an improvement upon the tram-stati:l for grinding-mills patented by me on the 29th day of October, 1867, and the construction and operation of the same are as follows:

A slotted plate, B, is secured by means of screws to the bottom of the stati' A, and for the reception of the staiblocks C. The said staff-blocks G consist of the metallic part c1 tric plate k, and set-screw l. The chucks It are provided with lugs m, which work in the eccentric apertures of the plate k, so that when the annular collar is rotated the said chucks I a-re made to approach and clasp the spindle o. The annular collar may be clamped lirmly in any desired position by means of the setscrew l.

The upper chuck-box p is of substantially the same construction and operation as the lower one, except that instead of a set-screw the nut q is made use of to clamp the annular collarf at any desired point.A

Having thus described the essential improvements of my present invention upon my former patent, l claim- 1. In combination with the staff', the staiblock, consisting of two parts, c1 audaz, having a vertical and longitudinal adjustment, as herein shown and described.

2. The clutch-box F, provided with the an- "nular collar f, eccentric g, chuck h, eccentric plate k, set-screw l, lugs m, working in the eccentric apertures ofthe plate k, the spindle o, the upper clutch-box p, and the staff, all constructed and operating as described.

In testimony that I claim the foregoing I have hereunto set my hand and seal this 9th day of August, 1872.
